We had a great time at Pupe's place.
It was as described and everything from check-in to check-out went to plan.
If you want something a little different, then this is the place for you. It would be good for 2 couples as there are 2 good sized rooms (we had the top room with balcony).
It's in Chinatown which is noisy. But I'd say all of Bangkok was noisy and describe the road as a quiet side street.
There's a quiet bar/restaurant down below. What more could you want?!
